EDWARD ROWE, OF INDIANA, PENNSYLVANIA.

STEAM CONDENSER AND AERATOR.

SPECIFICATION forming part of Letters Patent No. 554,539, dated February 11 1896.

Application filed May 25, 1895. $erial No. 550,630. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD ROWE, of Indiana, in the county of Indiana and State of Pennsylvania, have invented a new and Improved Steam Condenser and Aerator, of which the following is a full, clear, and exact description. I

The object of the invention is to provide a new and improved steam condenser and aerator which is simple and durable in construction, arranged to insure a quick condensation of the steam from an engine, and to relieve the latter of back-pressure, and also prevent water from the engine running back into the exhaust-pipe, and to aerate the water of condensation, so as to make it better for use in boilers.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.-

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement on the line 1 1 of Fig. 2. Fig. 2 is a sectional plan View of the same on the line 2 2 of Fig. 1. Fig. 3 is a sectional plan view of the distributer on the line 3 3 of Fig. 1 and Fig. 4 is a side elevation of the lower end of the baffle-plate.

The improved condenser and aerator is .provided with a steam-distributer A, provided with a conical top A and a correspondingly-shaped but inverted bottom A into which extends a pipe B connected with the exhaust of the engine, the said pipe 13 eX- tending a short distance above the bottom A as plainly indicated in Fig. 1. From the conical top A of the distributer A lead a series of short nozzles 0 extending into the short inlet-pipes D, held in the lower head, E, of a shell E, closed at its upper end by a head E.

It will be seen that exhaust-steam passing from the exhaust-pipe through the pipe B into the distributer A passes from the latter through the several nozzles O upward and through the inlets D into the shell E, thereby causing air to be drawn into the inlets D from the outside and on the under side of the shell,

so that air thus drawn into the shell E is mingled with the steam, and consequently a rapid condensation of the steam takes place within the shell without danger of back-pressure to the engine.

In the shell E are arranged a series of airpipes F, leading from one head E to the other head E and arranged alternately with the air-inlet pipes D. (See Fig. 2.) The pipes F, together with the pipes D, are preferably arranged in a circle, and inside of the said pipes is located abaffle-plate G, made circular and set at its lower end on the head E, to extend at its upper end within a short distance of the top of the head E The lower end of this baffie plate G is formed with notches or openings G, so that any water of condensation in the water-pipes of the shell can pass through the said openings to the center of the head E.

A second set of air-pipes H, and held in the heads E and E is arranged within the baffleplate G, and within this set of air-pipes extends a stack 1, attached to the top head, E and extending with its lower end a suitable distance from the lower head, E, as plainly indicated in Fig. 1. The stack I reaches upward and outward a suitable distance beyond the upper end of the head E so that the steam not condensed can pass through the said stack I to the outside.

In the lower head, E, and at or near the center thereof, is arranged a drain-pipe J for carrying 01f the water of condensation, the drain-pipe J being connected by a branch pipe J with the bottom A of the distributer A, so as to carry off any water of condensation that may accumulate in the said distributer.

A circular pipe K provided with an inletpipe K and connected with a suitable source of air supplysuch, for instance, as a pressure blower or pumpis located under the distributer A, and is provided with a series of nozzles K which extend through the bottom A of the distributor, through the said distributer and ashort distance into the nozzles O, as plainly indicated in Fig. 1. Bythis arrangement air under pressure may be forced through the nozzles C, so as to insure a ready outflow of the exhaust-steam from the distributer A through the nozzles 0.

It will be seen that by forcing compressed air through the nozzles C by the nozzles K the exhaust-steam in the distributer is forcibly ejected through the said nozzles O and inlet-pipes D into the shell. This action tends to cause a vacuum in the distributer and consequently in the exhaust-pipe and enginecylinder, thus relieving the engine of all backpressure and permitting it to work with greater power. Now it will be seen that by the arrangement described the steam passing from the engine to the distribnter A passes from the latter through the nozzles C in the shell E, to be there mixed or mingled with air drawn in by the steam through the inletpipes D. Thus the steam is rapidly eondensed, and the condensation is aided by the mingled steam and air coming in contact with the pipes F and II, through which circulates atmospheric air. Thus it will be seen that the mingled steam and air first pass upward in the outer part of the shell E, owing to the baffle-plate G, the steam and air then passing from the upper end of the shell downward and within the bathe-plate G and pipes H to finally permit the steam not condensed and air to pass into and out of the stack 1.

On the under side of the top A of the distributer A is arranged an annular flange A so that any water of condensation which is thrown up by the engine through the pipe B is caused to flow down the said flange and drop upon the bottom A without danger of the said water being carried by the exhaust steam through the nozzles 0.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A steam condenser and aerator, comprising a shell provided with air-inlets, steamnozzles extending from a steam-distributer into the said air-inlets, to cause the exhauststeam passing through the nozzles and air-inlets to draw in the air through the inlets, to insure a mingling of the air and steam within the said shell, and nozzles connected with a compressed-air supply and extending into the said steam-nozzles, substantially as shown and described.

2. A steam condenser and aerator, comprising a shell formed with a series of short airinlets in its lower head, a steam-distributer connected with a steam-exhaust, a series of steam-nozzles extending from the said distributer into the said air-inlets, and a stack extending into the said shell, substantially as shown and described.

3. A steam condenser and aerator, comprising a shell formed with a series of short airinlets in its lower head, a steanrdistributer connected with a steam-exhaust, a series of steam-nozzles extending from the said distributer into the said air-inlets, and a bafiieplate arranged within the said shell and inside of the said air-inlets, the said baffle-plate extending from the lower head of the shell to within a short distance of the top thereof, substantially as shown and described.
